Hi all,

Just bought this power supply and it turns out to be 24V as opposed to
12 as I'd hoped. It's a heafty beast and should be good for running my
HF mobile if I can drop the voltage down to 13.8 whilst retaining about
20 amps for the rig's TX current draw. I know I can buy a commercial
dropper, but that'd be cheating, so can anyone suggest how I might
acheive such a device through HB-ing? Which active devices would be
best for this purpose? I'd like over-voltage protection built-into any
design put forward if possible. Any pointers, please.

Thanks!
